Abstract
The utility model relates to a throttling device for a cooling heat pump system. The throttling device comprises an electronic expansion valve (1) and is characterized in that the throttling device also comprises a deformation connecting pipeline (2), wherein the expansion valve (1) is connected with the deformation connecting pipeline (2) in parallel or in series. Because the utility model adopts the deformation connecting pipeline to replace a capillary pipe and coordinate with the electronic expansion valve for throttling, the same throttling effect with the capillary pipe can be achieved, and the cost is reduced.
Description
Technical field
The utility model is a kind of throttling arrangement of refrigeration heat pump system, belongs to the improvement technology of the throttling arrangement of refrigeration heat pump system.
Background technology
Existing refrigeration heat pump system generally adopts electric expansion valve and capillary to carry out throttling, electric expansion valve is connected with the capillary serial or parallel connection, and capillary is finished roughly throttling and regulated, and electric expansion valve is finished accurate adjusting, but this throttling arrangement is because of being provided with capillary, so cost is higher.
The utility model content
The purpose of this utility model is to provide a kind of cost low in order to address the above problem, and can reach the throttling arrangement with the refrigeration heat pump system of the same restriction effect of prior art.
The utility model is a kind of throttling arrangement of refrigeration heat pump system, comprise electric expansion valve,
The distortion connecting line, electric expansion valve and distortion connecting line are in parallel or be connected in series.
The medium position flattening deformation of above-mentioned distortion connecting line forms.
The medium position of above-mentioned distortion connecting line is formed by its two ends internal diameter contraction distortion.
The utility model carries out throttling owing to adopt the distortion connecting line to replace capillary to cooperate with electric expansion valve, not only can reach the restriction effect same with capillary, and reduce cost.
Description of drawings
Fig. 1 is the structural representation of embodiment 1 of the present utility model.
Fig. 2 is the structural representation of embodiment 2 of the present utility model.
The specific embodiment
Embodiment 1:
The throttling arrangement of the utility model refrigeration heat pump system as shown in Figure 1, comprises electric expansion valve 1, distortion connecting line 2, and electric expansion valve 1 and distortion connecting line 2 are connected in parallel.In the present embodiment, the medium position flattening deformation of above-mentioned distortion connecting line 2 forms.
Embodiment 2:
The present embodiment difference from Example 1 is: electric expansion valve 1 and distortion connecting line 2 are connected in series, and the medium position of distortion connecting line 2 is formed by its two ends internal diameter contraction distortion.
Claims (3)
1, a kind of throttling arrangement of refrigeration heat pump system comprises electric expansion valve (1), it is characterized in that also comprising the distortion connecting line (2), electric expansion valve (1) and the distortion connecting line (2) parallel connection or be connected in series.
2, the throttling arrangement of refrigeration heat pump system according to claim 1 is characterized in that the medium position flattening deformation of above-mentioned distortion connecting line (2) forms.
